In the provides a practical example. The following command uses scp to copy a large file. If the process takes longer than an hour, it is killed:
waitmax 3600 scp bigfile.tar.gz somehost:/tmpWaitmax is released under the GPLv2 and can be downloaded from the author’ homepage here. Both the source code and a statically linked RPM package are available.
